Zoom on the Ryobi RY905500

In summary, the Ryobi RY905500 is a portable generator especially useful for:

  • RV travellers looking for even more independence
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from and any relevant emission compliance details.

Power & Run Time

The Ryobi RY905500 in use

The Ryobi RY905500

The Ryobi RY905500's engine, 420 cc Ryobi OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 5500W and reaches a peak wattage of 6875W.

Enjoying a noise rating of 78 dBA (less noisy than a dishwasher), this generator gets running thanks to Ryobi's EasyStart pull-start mechanism (more information below).

With a full tank, the RY905500 can operate for around 10 hours at 50% load (fuel consumption around 0.6 GPH), thanks to its fuel capacity of 6 gallons.

The quite high THD (<20%) of the RY905500 makes it unsuitable for powering sensitive of electronic devices.

Several examples of what the generator may allow you to power simultaneously are:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel provides the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Since the RY905500 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The design of the Ryobi RY905500 is a typical, open frame, with the dimensions of L31.5 x W29 x H24 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 192 pounds. However, its challenging mobility is solved by a wheel kit and a folding handle, which will ease its displacement, once it is on the floor.

EasyStart Mechanism

Ryobi's 3-step EasyStart mechanism

The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:

  1. Put the engine switch on the “ON” position, and place the lever on the “START” position
  2. Pull the recoil until the engine runs
  3. Let the engine run 15 to 30 seconds and place the lever on the “RUN” position

The RY905500's control panel

To help you monitor the RY905500's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the classic documentation and a user manual to get you promptly started, the Ryobi RY905500 also comes with some accessories: oil and tool kit are included.

Emissions

The Ryobi RY905500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Ryobi RY905500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY905500 compare to generators of similar power (between 5000 and 6000 W).

  • Having a dry weight of 192 lbs, the Ryobi RY905500 belongs in the expected weight range for generators which produce 5000 to 6000 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the Champion 100519, with a dry weight of just 121 pounds.
  • When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 78 dBA is on the noisier side. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
  • As far as autonomy is concerned, providing 10 hours of runtime with a full tank at a 50% load, the RY905500 falls into the low end in comparison with other devices of a comparable power output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Cat RP5500, with 15 hours .
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. As this generator uses an estimated 0.6 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse WGen5500, with a fuel consumption of 0.44 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 5000-6000W generators, the Ryobi RY905500 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
